test-driven-development

Start test-driven development by writing a failing test before any implementation code. Follow the Red-Green-Refactor cycle: write a failing test, implement minimal code to pass it, then refactor.

Common testing anti-patterns in TDD include skipping the failing test phase or writing excessive code before testing. This Skill identifies and discourages these pitfalls to ensure code quality and prevent regressions.

Use the Red-Green-Refactor cycle in agile development whenever adding a new feature or fixing a bug. It enforces writing tests first, ensuring reliable software and preventing future regressions during code changes.

Yes, test-driven development helps with debugging and preventing code regressions. By enforcing a rigorous testing process before implementation, it ensures code quality and creates a reliable safety net for future refactoring.

You can use the TDD methodology for refactoring existing software code by ensuring tests cover current behavior first. The Red-Green-Refactor cycle guides safe modifications while maintaining code quality and preventing regressions.
